as required for homodyne detection. One pump was tuned to the resonance near 1560.9 nm (the P1 resonance), and the principal resonator was actively locked to this pump to maximize the circulating pump power in the principal ring. The frequency of the other pump was tuned to a second resonanc...
To the best of our knowledge, this study represents the first report utilizing nonstoichiometric CuInS2 nanocrystals as a photon-harvesting sensitizer comprised of a photoanode and photocathode in QDSSCs; also unique to this report, these nonstoichiometric CuInS2 nanocrystals were formed by simply ...
Light, as an electromagnetic wave, has two essential components: amplitude and phase1. Optical detectors, usually relying on photon-to-electron conversion (such as charge-coupled device sensors and the human eye), measure the intensity that is proportional to the square of the amplitude of the ...
Silicon photonics is currently the leading technology for the development of compact and low-cost photonic integrated circuits. However, despite its enormous potential, certain limitations, such as the absence of a linear electro-optical (EO) effect because of the symmetric crystal structure of silicon...
light a fire under To urge or move to action. light at the end of the tunnel The prospect of success, relief, or escape after strenuous effort. [Middle English, from Old English lēoht, līht; see leuk- in Indo-European roots.] Usage Note: Lighted and lit are equally acceptable as pas...
In this experiment, the light begins and ends its existence acting as a particle – a photon. But when one of these photons hits a boundary between the layers of material, it creates waves at each surface, and the traveling light waves interfere with each other just as opposing ocean waves...
believed to be more qualified for producing sophisticated 3D devices even with sub-micrometer-scale details, such as bio-mimetic morphologies/structures, because of their very high spatial resolution (even to the sub-30 nm regime for two-photon polymerization that uses a femtosecond laser) (Fig....
Our Photone grow light meter app measures photosynthetically active radiation (PAR) as PPFD in µmol/m²/s, calculates the daily light integral (DLI) in mol/m²/d, and measures illuminance in foot-candles or Lux. It also allows you to measure light temperature in Kelvin which can hel...
LS-pfOCE is also able to quantitatively characterise the variations inG′ andRas a function of distance to the cell body in 3D space (see “Methods” for details of this analysis). A decreasing trend inG′ as a function of distance is apparent within the pericellular space (within 30 ...
single-photon detection efficiency, this implies a photon flux of the order of 0.2 photons per pulse, per full pixel area. The combination of single-photon sensitivity and picosecond temporal resolution make it very difficult for detector technologies such as intensified CCD19to achieve the results ...
